Description

Technical Field

[0001] This utility model relates to the field of food cooking appliances, and in particular to an air fryer. Background Technology

[0002] In existing technologies, the baking tray in an air fryer is placed directly into the inner pot or the pot itself. However, for some foods, it is not easy to remove them during cooking, and it is necessary to flip the air fryer to pour them out. During this flipping process, the baking tray is prone to falling out because there is no cover or fixation. For example, for small and numerous items such as French fries, popcorn chicken, and peanuts, it is more convenient to pour them out directly. If the baking tray falls out, the food is likely to spill out of the container or burn the operator, which seriously affects the use of the air fryer. Utility Model Content

[0003] The purpose of this invention is to provide an air fryer that uses accessories to partially cover the baking tray, thus preventing it from falling off during the flipping process.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] An air fryer includes an inner pot and a hot air assembly located on the upper part of the inner pot. The lower part of the inner pot extends to form at least two overlapping portions. An accessory is attached to the overlapping portion, and the accessory forms a slot in which a baking tray is inserted. When the food is baking, the accessories create downward pressure. When the food is being removed, the inner pot is flipped over, and the accessories form a supporting surface that acts on the baking tray. The fitting is a silicone component, which is attached to the overlap at the lower part of the inner liner.

[0006] Furthermore, the fitting has a protruding structure that protrudes towards the inner wall of the inner liner at a position near the inner liner.

[0007] Furthermore, the edge of the baking pan is provided with a notch, and the extended portion of the notch and both sides of the notch overlap with the overlapping portion.

[0008] Furthermore, the extension is positioned toward the apex of the inner liner, and the overlapping area formed by the extension is larger than the overlapping area formed on both sides of the notch.

[0009] Furthermore, the extension and the two sides of the notch form an airflow channel toward the bottom of the inner pot and the baking pan.

[0010] Furthermore, a ventilation gap is formed between the baking pan and the inner wall of the inner liner, and a guide rib is formed by the protrusion of the edge of the baking pan, which causes the airflow in the ventilation gap to flow downward or towards the airflow channel.

[0011] Furthermore, the slot has an inclined locking groove facing downwards near the inner liner, and the edge of the baking pan has a locking part that matches the locking groove.

[0012] Furthermore, the overlapping part is an L-shaped structure located at the bottom corner of the inner liner, and the L-shaped structure forms a semi-enclosed structure along the top of the inner liner.

[0013] Furthermore, a portion of the base within the semi-enclosed structure protrudes, forming an arc-shaped rib structure extending from the inner wall of the inner liner towards the center of the inner liner.

[0014] Furthermore, a guide path is formed between the two ends of the L-shaped structure and the convex rib structure.

[0015] The beneficial effects of this utility model are as follows: In this invention, by adding overlapping parts and fittings, the baking tray will not fall off during flipping, thus improving safety, especially for cooking small and numerous ingredients such as French fries, popcorn chicken, and peanuts, where flipping is necessary to remove the ingredients.

[0016] In this invention, the gaps in the fittings allow hot air flowing down the inner wall to be guided into the space between the bottom of the inner liner and the baking tray, and then discharged through the vent in the middle of the baking tray, thus forming a better circulation path and ensuring even heating.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0019] See attached document Figure 1-9 As shown, an air fryer in this embodiment includes an inner pot 100 and a hot air assembly 200 located on the upper part of the inner pot 100. The lower part of the inner pot 100 extends to form at least two overlapping portions 110. In this embodiment, unlike the prior art where a baking tray 300 is directly placed on the overlapping portion 110, an assembly 400 is added. The assembly 400 overlaps the overlapping portion 110 and forms a slot 410. The baking tray 300 is inserted into the slot 410 by means of its edge, thus completing the assembly of the two.

[0020] Compared to a separate support, the fitting in this embodiment has multiple effects. For example, during normal baking, the food is placed on the baking tray and suspended inside the inner liner 100. The fitting 400 exerts downward pressure due to gravity, pressing down on the baking tray 300 and causing it to align with the overlapping part 120. When the food is removed, the inner liner is flipped, and the fitting 400 forms a bearing surface on the baking tray 300, preventing it from easily falling off. To increase the force between the fitting 400 and the inner liner 100, a silicone component is used as the fitting. Its own adhesive properties give it a strong adhesion to the inner liner 100, making it less likely to fall off. If there were only a supporting force, the baking tray would fall off directly after flipping, affecting its use.

[0021] Of course, at this time, the overlapping part 110 can form a sloping structure, which can guide some airflow into the space below the inner liner 100 and the baking tray 300. In this embodiment, in order to ensure the stable assembly of the baking tray, a downward blocking component is provided above the baking tray, that is, an assembly 400 is provided above the overlapping part 110, and the entire assembly 400 forms a large overlapping support surface. In the prior art, the assembly of the baking tray is just a simple support, which not only makes it difficult to meet the cooking needs, but also exposes the operating part of the high-temperature grill, which is prone to burns and affects the use.

[0022] In this embodiment, the fitting 400 forms a covering surface when the food is baking, due to gravity and the downward pressure, thus creating a relative downward pressure. When the food is being removed and the inner pot needs to be flipped, the fitting 400 forms a bearing surface acting on the baking pan 300, preventing it from falling.

[0023] To enhance the assembly stability between the silicone component and the inner liner 100, a protruding structure 420 is provided on the component 400 near the inner liner 100, protruding towards the inner wall of the inner liner 100. If the outer side of the component 400 is a flat plane, it will form an interference fit with the inner wall of the inner liner 100, lacking strength support. The protruding structure 420, however, forms an independent support point, increasing the support force and allowing it to be assembled relatively stably with the inner liner 100.

[0024] Here, the assembly 400 and the baking tray 300 are interference-fitted, creating an assembly gap between them. At this time, the airflow will pass through the assembly gap and enter between the bottom of the baking tray 300 and the inner liner 100. The downward pressure of the assembly at this time helps the airflow to move downward, accelerating the flow speed and making the temperature more uniform.

[0025] See attached document Figure 4 As shown, in this embodiment, the inner liner forms an assembly cavity, and the baking pan 300 in the assembly cavity has a notch 310 at the edge. The innermost part of the notch 310 extends to form an extension 320. The two sides of the notch 310 and the extension 320 form three overlaps with the overlapping part. Compared with the overall overlap, this distributed overlap not only saves the material of the entire baking pan, but also has more overlap points, ensuring support.

[0026] In this embodiment, the three overlapping connections can form a triangle. This overlapping method utilizes the stability of the triangle to ensure the stability of the bottom of the assembly. If the food is too heavy or shakes, the overlapping support will also be stable, reducing the movement of the baking tray.

[0027] Specifically, during setup, the extension 320 in the baking pan 300 can be oriented towards the top corner of the inner liner 100. For example, four notches can be provided, and then matched with the four top corners. In this case, since the notches are arc-shaped, their sides only slightly overlap with the overlapping part 110. Therefore, the extension can be made slightly larger, so that the overlapping surface area formed by the extension 320 is larger than the overlapping surface area formed by the sides of the notch 310. In this embodiment, the extension can be a cuboid structure. In this case, the cuboid and the sides of the notch form an airflow channel towards the bottom of the inner liner, allowing the airflow to be guided through this channel to the bottom, facilitating upward flow from the air outlet 330 in the middle of the baking pan 300.

[0028] To concentrate and guide the heat flow from the inner wall of the inner liner 100 to the bottom, a ventilation gap is formed between the baking pan 300 and the inner wall of the inner liner 100, allowing airflow from the inner wall of the inner liner to flow through the ventilation gap. A guide rib 340 is formed by protrusions at the edge of the baking pan 300. The addition of the guide rib 340 blocks the airflow near the bottom inner wall of the inner liner 100, forcing it to move only downwards within the ventilation gap. An arc is set at the edge of the guide rib 340, forming a guide path from the middle of the side wall towards the top corner, thus causing the airflow within the ventilation gap to flow downwards or towards the airflow channel, providing a basis for subsequent flow.

[0029] In this embodiment, to ensure that the baking tray 300 and the assembly 400 are assembled as seamlessly as possible and securely, the slot 410 is provided with a downward-sloping locking groove 430 facing the center of the inner liner 100 near the inner liner 100. The edge of the baking tray 300 is provided with a locking portion 360 that matches the locking groove 430. In this embodiment, the locking portion is provided at the extension 320, thus completing the assembly at the very center.

[0030] In this embodiment, a reinforcing rib 370 is formed by protrusions on the baking tray. The reinforcing rib 370 extends from the air outlet 330 of the baking tray 300 outwards until it reaches the position where it contacts the slot 410, thereby enhancing the overall strength of the baking tray 300. In this embodiment, the reinforcing rib 370 can also be an extension of the surrounding guide rib 340 toward the notch 310. It can be seen that it can be set to the deepest part of the extension 320 and set at the top corner to ensure increased strength.

[0031] For ease of use, the cross-section of the fitting 400 is square. The fitting 400 is then assembled with the inner liner 100, etc. The silicone parts have adhesive properties, allowing the user to pull the baking tray 300 and fitting 400 out of the inner liner 100 for disassembly. However, when the inner liner is flipped, the large supporting surface formed by the fitting 400 secures it to the baking tray 300 within the inner liner 100, preventing it from falling off and ensuring stability.

[0032] To provide support for multiple surfaces, the overlapping portion 120 is an L-shaped structure located at the bottom corner of the inner liner 100, and the L-shaped structure forms a semi-enclosed structure along the top of the inner liner 100. In this embodiment, the L-shaped structures are distributed in the X and Y directions of the inner liner 100 to form an enclosure, and this semi-enclosed structure also allows airflow to flow from the outside towards the inside of the semi-enclosed structure.

[0033] To direct the airflow within the semi-enclosed structure towards the air outlet 330 at the center of the baking pan 300, a portion of the base within the semi-enclosed structure can be raised to form an arc-shaped rib structure 350 extending from the inner wall of the inner liner towards its center. This rib structure 350 allows airflow from the edge of the L-shaped structure to enter the center. Multiple arc-shaped rib structures 350 can be installed to further guide the airflow.

[0034] Because the airflow at the gap 310 is diverted, a guiding path is formed between the two ends of the L-shaped structure and the rib structure 350. This allows the airflow at the ends of the L-shaped structure in both the X and Z axes to be guided towards the vicinity of the rib structure 350.

[0035] In actual use, the heat generated by the hot air component 200 moves outward through the cooling fan and then enters the inner wall of the inner pot 100. Then, through the airflow channels and gaps at the notch, the airflow is forced to flow downward between the base of the inner pot 100 and the baking tray 300. Then, guided by the rib structure 350, the airflow flows to the air outlet 330 in the middle of the baking tray 300, and then flows upward, circulating back into the hot air component 200, forming a circulating airflow path. The airflow then circulates repeatedly along the inner wall and the middle of the inner pot 100, forming a relatively stable temperature airflow, which makes the food heated evenly and has a good cooking taste.

[0036] Air fryers, as commonly used cooking appliances, typically suspend the baking tray 300 within the inner pot 100, and then the heating element 110 directly heats it, such as by using a heating tube. However, in this method, the assembly of the baking tray 300 is not secure enough and it is easy to fall off. By adding the mounting accessory 400 in this embodiment, a certain assembly limit is formed, making it less likely for the baking tray 300 to flip inside the inner pot 100. This makes it safer and more stable when shaken. In addition, with the addition of various gaps, the airflow circulation speed is accelerated, making the temperature inside the inner pot as uniform as possible. This ensures that the food is heated evenly by the airflow, reducing problems such as burning, and improving the taste and cooking efficiency.

[0037] In this embodiment, the entire heating assembly 110 and the fan are assembled in the head cover 600. Then, the head cover 600 and the bottom heat insulation cover 500 cooperate to form the outer shell, while the inner liner 100 is suspended and supported in the heat insulation cover 500 by the support liner 130 and the support leg 140.
